Bulk Stores like Costco or Sam's Club can be great for getting bulk foods for less, but there are some things you'll almost always pay more for. One of the things you'll want to skip? Fresh foods.

Personal finance weblog Squakfox took a deeper look at whether bulk stores were worth the membership fees, driving distances, and long lines. In their price checking, they found that fresh foods tended to be more expensive at the bulk stores:

Costco's fresh produce tends to be more expensive than Superstore, based on unit price. For example, Costco's gala apples sell for $2.13/kg while Superstore offers the deal at $1.28/kg. I also found Costco to be more pricey for fresh vegetables, chicken breasts, milk, cheese, and coffee.

Frozen foods, on the other hand, are something you'll almost certainly want to pick up at Costco rather than your local store. Not only are they cheaper, but they're also higher quality. In fact, the more "packaged" a product, the better the deal at bulk stores—so keep that in mind when you're shopping and you'll be sure to save the most money possible.
